The AZ vaccine has had data issues in its trial and the FDA is waiting on the US trial arm to finish (likely a month from now) before making a decision. The J&J vaccine has just released data and will likely be authorized in a couple weeks, but manufacturing issues mean that we won’t see tens of millions of doses until April. Novavax is in a similar boat, they won’t have much manufacturing available until late spring and their US trial only started in December so it will run until April.
